POWER-TRANSLATING APPARATUS. V

Be it kIlOWILdJllflll I, JOSEPH SACns, a citizen of the United States ofAmerica, residing at Hartford, in the county of Hartford and State ofConnecticut, have invented an Im provement in Power-TranslatingApparatus,

of which the following is a specification.

Heretofore dynamos have been driven by prime 'movers of variousdescriptions for generating electricity and supplying the same toelectric motors coupled to devices and ma chines to be operated.Apparatus of this nature have been applied to motor vehicles tow-hich myimproved power translating ap-- paratus is'particularly applicable.Where ydro-carbon explosive engines have been employed as prime moversin motor vehicles it has been necessary, owing to the limited torqueeffect of the engine, to provide mechanical gearings in varying ratios,any of w-hichimight be connected at will to the engineshaft to producean increased or decreased torque eifect at thqvehicle wheels with aninversely varying speed, and one of the objects of my invention is torovide a power translating apparatus app icable to motor vehicles orother devices for transmitting power from hydro-carbon explosive enginesor other prime-movers and delivering the power with inversely variabletorque and speed at the drivingend without exceeding t 1 e limit'of theenergy output of the prime mover, and devices whereby, if occasiondemands, the vehicle may be driven directly from the prime mover.-

In carrying out my invention I preferably unite in one unit, twoarmatures and'a common magnetic field system having the functions ofboth an electric generator and an electric motor and byemploying'special means for controlling and-regulating the A magneticflux through one or both armatures The armature or armatures in whichthe elecwithout the use of field resistances or seriesparallel switches,I obtain a variation in speed and torque eifectat the driving end asgreat as if each of the functions were developed in separate andindividual machines.

tric current is produced and those in which it is transformed intomechanical energy, may

' be ma neticall i in series with each other and with afield magnet.

In the series arrangement, which I prefer,

the magnetic flux passes through the field magnet and both armaturessuccessively,

. andis setup by a'common field coil or coils.

These coils are preferably series or compound connected but may be shuntponnected or separately excited, and when once adjusted need not bevaried manually to produce the variation in speed and torque at themotor end. With the magnetic series arrangement of armatures and fieldmagnet I preferably employ a magnetic shunt of permeable material whosemagnetic reluctance is less than that of the air-gap and cores of eitherarma ture and so arranged as to be adjustably movable towards or awayfrom or in contact with the field magnet pole-pieces of either the.generator or motor armatures. By placing this magnetic shunt across thepoles of eitherarmature the flux through the same will be decreased inthe ratio of the magnetic conductors of the air-gap and core of thatarmature to the conductors of the magnetic shunt, and .the totalmagnetic flux is in-. creased by the lower reluctance due to themagnetic shunt thereby increasing the flux through the other armature.Therefore by magnetically shunting one armature its field is decreasedwhile that of the other is increased and hence a drop in the voltage dueto magnetically shunting the generator armature, causes an increasedfield and consequent increased torque at the motor end with a decreasedvoltage at the motor armaand this is madepossible by reducing the fluxthrough the generator armature. This results in acor'responding loweringof the generated electro-1notive force and a consequent further decrease1n the motor armature speed until the desiredcurrent is obtained.

At the same time the fiuX through the motor armature core hasbeen-increased due to a decrease in the magnetic reluctance of the fieldsystem by the shunting of the generator armature amd also due to theincreased cur rent flow in the field magnet cores which is automaticallyincreased with the increase of herein described may serve as either amulti armature generator or motor as well as a generator motor or motorgenerator, and the magnetic shunt regulating devices may or may not beemployed when so used, as is set forth in [letters Patent N 0. 781968,granted to me February 7th, 1905, for dynamo electric nuiehine of whichthe present case is, a division.

In the drawing, Figure 1 is a plan view showing the application of myimproved power translating apparatus to a motor vehicle, and Fig. 2 is alongitudinal sectional elevation of the same.

Referring particularly to the drawing, 2 represents the. frame of amotor vehicle: 3 represents a hydro-carbon or other engine suitablymounted upon supports 4; carried by the frame 2.

5, i5, 7 and represent field poles of a dynamo-motor electric machinewhich is suitably mounted upon supports 9 also carried by the said frame2.

10 represents a dynamo-armature operating between the field poles 7 and8, and 11 the motor armature operating between the field poles 5 and 6.The engine power shaft 32 is preferably connected to thedynamoarmatureshaft by a clutch 13, and the driveshaft l-cl of the vehicle ispreferably connected to the shaft of the motor armature through adifferential gear 15, shaft 16and clutch 17.

As shown and described inmy application hereinbefore referred to in thisform of apparatus I employ a bar 18 which is made of well annealed ironor other equallypermeable material. This bar 18 is connected to sinus35? mounted in suitable bearings 20, carried by frames 21, which latterare secured to the sides of the machine. The bar 18 thus mounted isadapted to be moved toward, into contact with. or away from the fieldpolepieees of either the dynamo or mp'tor armature, and as illustrated,may be operated riirmi'gh the intervention of the lever" 22, sprockets"3i, and a chain or other connection 25.

The (.lynaino and motor armatures are electrically connected in anydesired manner, but pi rably in series with each, other and with theneld circuits.

As illustrated in Fig. 1 the electric circuit may contain a switch26-and the shafts of the motor and dynamo-armatures are nm-mallydisconnected, and the adjacent ends of the same are provided with themembers of an interlocking clutch 27 or any other form of clutch knownin the art adapted to connect said shafts in order that in case ofnecessity the engine may drive the vehicle directly through theseshafts.

It will be understood that 1 do not limit myself to any particular formof either the electrical or mechanical devices for connect ing thesource of power to the driven member, nor do I limit myself. to themeans for delivering the variable speed and torque through theelectrical devices, as many different arrangements are obviouslyavailable, and it will be apparent that the dynamo and motor may beseparate machines, or embodied in one machine, and ineither case thearmature shafts may-be in alinement or in any other relation to eachother, as set forth in my application hereinbefore referred to, and alsothat the clutch for coupling the dynamo and motor armature shaftstogether may be of any well known type and operated in any d siredmanner.
